Answer:

B

Step-by-step explanation:

Using the exact values

cos150° = - cos30° = - \frac{\sqrt{3} }{2}

sin150° = sin30° = \frac{1}{2}

Given

z = 4(cos150° + isin150° ) , substitute values

  = 4(- \frac{\sqrt{3} }{2} +  \frac{1}{2}i )

  = - 2\sqrt{3} + 2i , that is

(- 2\sqrt{3}, 2 ) → B

Which is the better buy a 3 pound ham for $5.70 or 5 pounds for $8.75
tekilochka [14]

Answer:

The larger ham is the better buy.

Step-by-step explanation:

In order to determine the better buy, divide both of the prices by their weight to get the price per pound of ham.

5.70/3 = 1.90 per lb

8.75/5 = 1.75 per lb

Therefore the 5 pound of ham is a better buy.
